Maternal anaphylaxis associated with GBS IAP occurs, but any morbidity ...
Additionally, those with penicillin allergies can usually tolerate cephalosporins (another group of β-lactam) because the immunoglobulin E (IgE) cross-reactivity is only 3%. [5] Penicillin was discovered in 1928 by Scottish scientist Alexander Fleming as a crude extract of P. rubens. [6]
